  • Attempting to update Amazon Route53 using a script, but domain is not being updated

    - by ks78
    I have several Amazon EC2 instances, running Ubuntu 10.04, with which I'd like to use Amazon's Route53. I setup a script as described in Shlomo Swidler's article, but I'm still missing something. When the script runs, it doesn't return any output, which I initially assumed meant it ran correctly. However, when I check the DNS records using MyR53DNS, there are no entries for my instances. Here's my script: #!/bin/tcsh -f set root=`dirname $0` setenv EC2_HOME /usr/lib/ec2-api-tools setenv EC2_CERT /etc/cron.route53/ec2_x509_cert.pem setenv EC2_PRIVATE_KEY /etc/cron.route53/ec2_x509_private.pem setenv AWS_ACCESS_KEY_ID myaccesskeyid setenv AWS_SECRET_ACCESS_KEY mysecretaccesskey /user/bin/ec2-describe-instances | \ perl -ne '/^INSTANCE\s+(i-\S+).*?(\S+\.amazonaws\.com)/ \ and do { $dns = $2; print "$1 $dns\n" }; /^TAG.+\sShortName\s+(\S+)/ \ and print "$1 $dns\n"' | \ perl -ane 'print "$F[0] CNAME $F[1] --replace\n"' | \ xargs -n 4 $/etc/cron.route53/cli53/cli53.py \ rrcreate -x 60 mydomain.com Does anyone see a problem with this script? If its not the script, what else could be preventing my Route53 domain from being updated? I am using the Security Groups to IP-restrict the instances. I've tried opening port 53, but that didn't seem to have an effect. Is there another port that Route53 uses? I'd appreciate any help or guidance the ServerFault community can offer. Let me know if you need any further info.

  • can't find port 22 traffic under VirtualBox

    - by telliott99
    I'm trying to learn to use tcpdump. I thought I'd eavesdrop on my ssh login. The setup is a bit unusual, I have OS X Lion running VirtualBox, with Ubuntu running in the VM.

  • Outbound HTTP performance tuning recommendations

    - by Richard Gadsden
    I'll detail my exact setup below, but general recommendations for a better web-browsing experience will be useful. A nice checklist of things to try would be great! I have 600 users on a single site with an 8MB leased line. I get a lot of moans about the performance of "the internet" (ie web-browsing). What recommendations do the community have for speeding things up without just throwing more bandwidth at it? I expect I will end up buying some more, but good management tips are always valuable. My setup is this: Cisco PIX (515E) firewall on the edge of the network. It's just doing some basic NAT, and opening up a handful of ports to various bastion hosts (aka DMZ servers). The DMZ is just a switch that the servers are plugged into. ISA 2006 Enterprise array (two servers) connecting DMZ to the internal LAN, with WebSense Web Security filtering HTTP traffic so users can't look at porn or waste bandwidth on YouTube during working hours. I've done a few things - I've just switched my internal DNS over to use root hints, which halved DNS query latency from 500ms to 250ms. Well worth doing. I'm trying to cache more aggressively, but so much more of the internet is AJAXy and doesn't cache very well as compared to five years ago. Plus the 70GB of cache which felt like a lot a few years ago really isn't any more. I'm getting about 45% cache hits by number of requests, but only about 22% by size, ie larger objects are less likely to be cached. Latency seems to be part of the problem. Is that attributable to the bandwidth problem, or are there things I can look at to try to reduce latency even on heavily-loaded bandwidth?

  • Router slowing my connection?

    - by Roberto
    I have a Linksys WRT54G and I pay for a 12Mbps connection. I've been testing my connection using speedtest.net for many days and always get 8Mbps. I called the support and they told me to bypass the router and test. I did it and got 16Mbps (much more than I pay for), so I thought "this guy just changed my speed so can he blame my router", and he blamed it. But to my surprise, everytime I bypass the router I get 16Mbps and when I use the router I get 8Mbps. Is this guy trolling me somehow (configuring the VOIP-modem-stuff to different profiles depending o the MAC address connecting to it) or is my router a POS? How can I find out? I don't know what's the thing the router connects to, it's a kind of VOIP adapter; the link is this one, but unfortunately I don't think you'll understand because it's in Portuguese. I know they can remotely connect to it, that's the origin of my conspiracy theory :) I just tested wired to the router and got 10Mbps (and still 8Mbps on wifi and 16Mbps without router) O_o I'm 5cm away from my router, so no obstacles to interfere, right? ------ UPDATE ------- It's a WRT54G V8, I'm using firmware v8.00.7 (will install 8.00.8 tomorrow, but I saw that it's only a minor fix to UPnP denial of service security vulnerability). Results: IPerf LAN-LAN: 80Mbps IPerf LAN-WLAN: 19Mbps (therefore we can ignore wireless issues/settings) I wasn't able to make the (W)LAN-WAN NAT-enabled test with IPerf, I get a connection refused error. I'm not sure if did it right: ran in server mode, configured router to forward that port to my IP and tried to connect to my internet IP that got from this site. I don't think there is a way to disable NAT using this firmware. Question: Let's suppose it's an underpowered hardware issue. Is it right to assume that custom firmwares could resolve the issue because they are possibly better implemented and would make better use of the router resources? I couldn't find any references pointing to wired performance improvements with the use of custom firmware.

  • SqlCmd : Login timeout expired from localhost

    - by mschr
    I've setup the instance SQLEXPRESS via SQL Server 2008 R2 installation, added a security login with all server roles, one called 'sqluser'. The server authentication is SQL Server and Windows Authentication mode. However, when i specify the -S property, login fails. There is no firewall enabled and SQL server even accepts connections from remote hosts. C:\Users\user>sqlcmd -U sqluser -P qwerty -Q "Select * FROM testdb.dbo.testtable" Output: integer ------- 1 2 3 4 (4 rows affected) However when specifying 'localhost' the query fails... Question is Why? C:\Users\user>sqlcmd -S localhost/sqlexpress -U cpt -P 1234 -Q "Select * FROM cpt.dbo.testme" Output: HResult 0x43, Level 16, State 1 Named Pipes Provider: Could not open a connection to SQL Server [67]. Sqlcmd: Error: Microsoft SQL Server Native Client 10.0 : A network-related or in stance-specific error ..... Sqlcmd: Error: Microsoft SQL Server Native Client 10.0 : Login timeout expired. Changing 'localhost' with '%COMPUTERNAME' is same result if someone would be wondering. The server is running as a LocalSystem instance.

  • Unable to stop chrome.exe *32

    - by chipperyman573
    So I was installing roboform today and was unable to stop the process chrome.exe *32... Even when I uninstalled chrome. This is the error I got: I used lockhunter and it said it was located in %appdata%\Local\Google\Chrome. However, it was unable to unlock, delete or rename. When I use explorer to delete or rename that folder, it says it's being used by Chrome. Even after restarting my computer it still does this. I've tried using the built in chrome task manager (Wrench View Background Pages) and I can't seem to find a process there that has the same amount of memory. I have run many, many virus scans, by: Microsoft security essentials AVG (Free version) Malwarebytes (Pro version) Norton 360 (Pro version) McAfee (Pro Version) Avira (Free version) Avast! Antivirus (Free version) None of which returned with any viruses.

  • How to generate customized sudoers files in puppet depending on the environment they're deployed to?

    - by gozu
    the sysadmins are present in the sudoers files of all environments, but other sudoers are not. Different environments all have slightly different sudoers. Most of the time, 90% of users are the same, and 10% vary so we cannot have only one sudoers file for everything. Right now, we are using puppet with 10 different files with names like sudoers.production1, sudoers.production2, sudoers.production3, sudoers.testing1, sudoers.staging1 and so forth. Puppet then picks the file to deploy based on the server's $domain (ex: dbserver.staging1.acme.com) or $hardwaremodel. It works fine but it's a nightmare to maintain so many files. I'd like to autogenerate sudoers files based on the server's domain and have only one big file with all the sudoers permissions for all users and all environments. Something that looks like: User_Alias ADMINS = abe, bob, carol, dave case $domain { "staging1.acme.com" { #add dev1,dev2,tester1,tester2 to sudoers file } "testing2.acme.com" { #add tester1, tester3, tester4 to sudoers file } What's the best way to go about this? Suggestions for alternatives are welcome. I'd appreciate any tips. Update 1: For security reasons, we'd rather not concatenate a bunch of files from a folder located on a puppet client in case someone puts a file in there (maliciously or not) and either breaks the combined file or inserts something in it. Most importantly, for usability, we'd like to keep the number of sudoers related files (fragment or complete) on puppet server to either 3 (prod/stage/test) or preferably 1 file. this file would (somehow) generate sudoers files on the puppet server and send one customized file to each puppet client. The purpose of this would be only searching for a username in a single file and removing it quicker than doing it on 11 files. When adding a user to a bunch of environments, it won't be as quick, but only one file would need to be opened and looked at, greatly reducing the chances of an omission. our Sudo version is 1.6.9p8 so we can't use /sudoers.d folder, only a sudoers file.

  • How to get the permissions right for /dev/raw1394

    - by Mark0978
    I recently upgraded one of my ubuntu machines to Karmic and I'm having trouble getting the permissions of /dev/raw1394 set to 0666. They only thing this machine is used for is recording audio from a firepod which uses /dev/raw1394 via jackd and there are no other FireWire devices connected, so security around this device is not really an issue. If I run as root, everything works as expected, but I have some folks that run the recorder that I don't want to have root access. However, I can't figure out which lines setup the perms I've tied this: /etc/udev/permissions.d/raw1394.rules:raw1394:root:root:0666 And I have this setup (default install) /lib/udev/rules.d/75-persistent-net-generator.rules:SUBSYSTEMS=="ieee1394", ENV{COMMENT}="Firewire device $attr{host_id})" /lib/udev/rules.d/75-cd-aliases-generator.rules:# the "path" of usb/ieee1394 devices changes frequently, use "id" /lib/udev/rules.d/75-cd-aliases-generator.rules:ACTION=="add", SUBSYSTEM=="block", SUBSYSTEMS=="usb|ieee1394", ENV{ID_CDROM}=="?*", ENV{GENERATED}!="?*", \ /lib/udev/rules.d/60-persistent-storage-tape.rules:KERNEL=="st*[0-9]|nst*[0-9]", ATTRS{ieee1394_id}=="?*", ENV{ID_SERIAL}="$attr{ieee1394_id}", ENV{ID_BUS}="ieee1394" /lib/udev/rules.d/50-udev-default.rules:# FireWire (deprecated dv1394 and video1394 drivers) /lib/udev/rules.d/50-udev-default.rules:KERNEL=="dv1394-[0-9]*", NAME="dv1394/%n", GROUP="video" /lib/udev/rules.d/50-udev-default.rules:KERNEL=="video1394-[0-9]*", NAME="video1394/%n", GROUP="video" /lib/udev/rules.d/60-persistent-storage.rules:KERNEL=="sd*[!0-9]|sr*", ATTRS{ieee1394_id}=="?*", SYMLINK+="disk/by-id/ieee1394-$attr{ieee1394_id}" /lib/udev/rules.d/60-persistent-storage.rules:KERNEL=="sd*[0-9]", ATTRS{ieee1394_id}=="?*", SYMLINK+="disk/by-id/ieee1394-$attr{ieee1394_id}-part%n" And I find these lines in /var/log/syslog Apr 30 09:11:30 record kernel: [ 3.284010] ieee1394: Node added: ID:BUS[0-00:1023] GUID[000a9200c7062266] Apr 30 09:11:30 record kernel: [ 3.284195] ieee1394: Host added: ID:BUS[0-01:1023] GUID[00d0035600a97b9f] Apr 30 09:11:30 record kernel: [ 18.372791] ieee1394: raw1394: /dev/raw1394 device initialized What I can't figure out, is which line actually creates that raw1394 device in the first place. How do you get /dev/raw1394 to have permissions 0666?

  • Fedora 16 can connect to samba share using smbclient but not in nautilus 3.2.1

    - by Nathan Jones
    I have a machine running Ubuntu 11.10 Server acting as a Samba server to share my home directory. Everything works fine on my Windows 7 machine, but on my Fedora 16 laptop, if I use Nautilus to try to access the share using smb://192.168.0.8/nathan in the location bar, it just has the loading cursor and does nothing. It never shows any errors, nothing. Using smbclient works just fine, but I'd like to get it working in Nautilus. I know that there can be problems with SELinux and Samba, so I created a file called booleans.local that contains samba_enable_home_dirs=1. My smb.conf file looks like this: # For Unix password sync to work on a Debian GNU/Linux system, the following # parameters must be set (thanks to Ian Kahan <<[email protected]> for # sending the correct chat script for the passwd program in Debian Sarge). passwd program = /usr/bin/passwd %u passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* . # This boolean controls whether PAM will be used for password changes # when requested by an SMB client instead of the program listed in # 'passwd program'.

  • How can I access a webDAV folder as a UNC share?

    - by Amar
    first of all I am just getting to know about webDAV and appreciate your patience. I have a virtual directory on IIS 6 (windows 2003) that is based on a network share on a file server different from web server. something like www.mysite.com/myreports where myreport is based on \myfileserver\reports. I have been asked by network folks to not use the UNC path like that for security reason and try to explore using webDAV. What I have been told is webDAV can give me a UNC path without requiring to open the ports required for a file server UNC path. Then I can use the new UNC path to map my virtual directory and my asp.net code will not require any change. Help: Being new to webDAV, I did some research over the web. I now can create a web folder in fileserver. I put IIS on file server as well. I can browse the content as http:://fileserver/mywebDAVreports which is based on reports folder. But I don't know how to get a UNC for this web folder to be able to map my virtual directory on web server. I appreciate any help on this. Regards, Amar

  • Why are symbolic links not working in MySQL?

    - by Eno
    I'm having an issue, I searched a lot but I'm not sure if it's related to a previous security patch. On the last version of MySQL on Debian Lenny ( 5.0.51a-24 ) I need to share one table between two db, those two db are in the same path ( /var/lib/mysql/db1 & db2 ). I created symbolic links for db2 pointing to the table in db1. When I query the same table from db2 I get this : 'ERROR 1030 (HY000): Got error 140 from storage engine' This is how it looks : test-lan:/var/lib/mysql/test3# ls -alh drwx------ 2 mysql mysql 4.0K 2010-08-30 13:28 . drwxr-xr-x 6 mysql mysql 4.0K 2010-08-30 13:29 .. lrwxrwxrwx 1 mysql mysql 28 2010-08-30 13:28 blbl.frm -> /var/lib/mysql/test/blbl.frm lrwxrwxrwx 1 mysql mysql 28 2010-08-30 13:28 blbl.MYD -> /var/lib/mysql/test/blbl.MYD lrwxrwxrwx 1 mysql mysql 28 2010-08-30 13:28 blbl.MYI -> /var/lib/mysql/test/blbl.MYI -rw-rw---- 1 mysql mysql 65 2010-08-30 13:24 db.opt I really need those symlinks, is there a way to make them working like before ? ( old MySQL-server is fine ) Thanks,

  • Mystery undeletable file

    - by Hugh Allen
    I can't delete C:\Config.Msi\75ce84f.rbf. it's not readonly, system or hidden it's not in use by another process (according to Process Explorer) the NT security permissions aren't the problem either - I am the owner and have Full Control ; as a double-check, the Effective Permissions tab shows that I have permission to delete. Yet trying to delete the file gives "Access is Denied" from both Explorer and cmd. I can however rename it or move it to another folder on the same drive. I can also read it and Virustotal says it's clean which is what I would expect (it's just a Windows Installer temp file - a copy of some DLL I think). The relevant line from Process Monitor is: 6:52:14.3726983 PM 112 Explorer.EXE SetDispositionInformationFile C:\Config.Msi\75ce84f.rbf CANNOT DELETE Delete: True Write 1232 Background: I'm using XP SP2. I recently repaired my Adobe Reader installation to make it the default browser plugin again instead of Foxit. (there seems to be no UI to do it otherwise?) So the installer did its thing and then asked to reboot. As is my habit when rebooting is inconvenient I declined the offer and ran pendmoves to find out what files the installer had scheduled to move / delete. It wanted to delete two files with .rbf extension (rollback files) located in C:\Config.msi\. (this applies to both even though I've been speaking about one). So I tried to delete them manually and couldn't. Does anyone have any ideas what could be preventing deletion? (and I don't think it's malware even though I'm not running AV at the moment)

  • Disabling CPU management

  • Authentication required by wireless network.

    - by Roman
    I would like to use a wireless network from Ubuntu. In the network drop-down menu I select a network (this is a University network I have an account there). Then I get a windows with the following fields: Wireless Security: [WPA&WPA2 Enterprise] Authentication: [Tunneled TLS] Anonymous Identity: [] CA Certificate: [(None)] Inner Authentication: [some letters] User Name: [] Password: [] I put there my user name and password and do not change default value and leave "Anonymous Identity"blank. As a result of that I get "Authentication required by wireless network". How can I solve this problem? I think it is important to notice that our system administrator tried to find some files (which are probably needed to be used as "CA Certificate"). He said that he does not know where this file is located on Ubuntu (he support only Windows). So, probably this is direction I need to go. I need to find this file. But may be I am wrong. May be something else needs to be done. Could you pleas help me with that?

  • Can't remotely connect through SQL Server Management Studio

    - by FAtBalloon
    I have setup a SQL Server 2008 Express instance on a dedicated Windows 2008 Server hosted by 1and1.com. I cannot connect remotely to the server through management studio. I have taken the following steps below and am beyond any further ideas. I have researched the site and cannot figure anything else out so please forgive me if I missed something obvious, but I'm going crazy. Here's the lowdown. The SQL Server instance is running and works perfectly when working locally. In SQL Server Management Studio, I have checked the box "Allow Remote Connections to this Server" I have removed any external hardware firewall settings from the 1and1 admin panel Windows firewall on the server has been disabled, but just for kicks I added an inbound rule that allows for all connections on port 1433. In SQL Native Client configuration, TCP/IP is enabled. I also made sure the "IP1" with the server's IP address had a 0 for dynamic port, but I deleted it and added 1433 in the regular TCP Port field. I also set the "IPALL" TCP Port to 1433. In SQL Native Client configuration, SQL Server Browser is also running and I also tried adding an ALIAS in the I restarted SQL server after I set this value. Doing a "netstat -ano" on the server machine returns a TCP 0.0.0.0:1433 LISTENING UDP 0.0.0.0:1434 LISTENING I do a port scan from my local computer and it says that the port is FILTERED instead of LISTENING. I also tried to connect from Management studio on my local machine and it is throwing a connection error. Tried the following server names with SQL Server and Windows Authentication marked in the database security. ipaddress\SQLEXPRESS,1433 ipaddress\SQLEXPRESS ipaddress ipaddress,1433 tcp:ipaddress\SQLEXPRESS tcp:ipaddress\SQLEXPRESS,1433

  • Oracle with Kerberos authentication and Windows 2003 Server as KDC

    - by Supaplex
    I am running Oracle 10.2 on a Windows 2003 Server SP2 which is also the domain controller on the network. I wish to switch authentication method from NTS to Kerberos. I have spent a lot of time trying to configure Oracle with Kerberos authentication from the Oracle Advanced Security option from the Net Manager utility. I have disabled NTS so Kerberos is promoted as the preferred authentication method. But as soon as the configuration is saved from Net Manager and I restart the Oracle server service, Oracle will not start. I don't know what Oracle is complaining about, because I don't know where to look for the Oracle error log. My first question is: how can I figure out what's bugging Oracle? My second question: is there a good tutorial for setting up Oracle on a Windows 2003 with Kerberos Authentication, where the Windows 2003 Server is the KDC? Maybe there is a book I can get? I have read Oracles own guide, but it is mostly for Linux/Unix. Thanks a lot!

  • SMB access from XP to Windows 2008 R2

    - by Pablo
    Here's the thing... I have a very slow file copy performance from Windows XP clients to Windows 2008R2 servers. Here are the facts: Windows XP to Windows 2K3: Fast Windows XP to Windows 2K8: Very Slow Windows 7 to Windows (any): Fast Despite the fact that the obvious solution would be to upgrade to Windows 7, well, we have 900 desktops so it's not an option in the short time. I have tried everything: Disabling SMB2.0, disabling security signatures, changing the TCP Window size, disabling the W2K8 auto tuning, upgraded the drivers, etc. We eliminated the network; both the server and the client are connected to the same core switch (no hops, no routers, same VLAN). Upon monitoring the network with a packet capture utility, we see that the SMB packets being exchanged between the W2K8 and the XP machines are very small packets (256 bytes); despite the fact that the MTUs are properly set (1500) and there is no fragmentation whatsoever. In fact, those SMB packets show, on the IP datagram, that the window is 65535 or close. The same trace, made using the same application but instead of using a W2K8 share uses a Windows XP share (and that goes FAST) shows SMB packets of 4096 bytes. I can post the traces if necessary. So, why does XP-W2K8 negotiation arrange for 24-bytes SMB payload, whereas the XP-XP negotiation arranges for 4096 SMB packets? Any ideas? I am running short of those...

  • Random Hard Freeze of Windows 7 (is Kaspersky to be blamed for this?)

    - by Christian Ivicevic
    The last few weeks I experienced a new strange behavior of my computer. Sometimes Windows 7 just freezes with no real reason at all. While listening to music for example the playback hangs and you can hear a very nasty sound. Neither mouse nor keyboard input is handled and everything is just stuck. Using Ubuntu this does not happen, so I think it is just a matter of driver issues or a Windows 7 bug. Furthermore I am really suspicious about Kaspersky (Internet Security 11) and so I let it perform a complete virus scan while no other app is running. At about 50% it happened again and I needed to restart the computer by holding the power button the bad way... A really weird thing is that playing Skyrim this happened once, however music playback did not stop. Only the framerate dropped to 0 and sometimes for a few seconds I am able to move. Therefore I am really confused as furthermore no bluescreen pops up. Memtest told me that everything seems to be alright... Can anyone explain me which data you need about my hardware and software (and which tools tools to use to gather the informatik) to be able to provide any help on my problem?

  • Windows Server (SBS) 2008 - Telephony service won't start (missing permissions)

    - by Uri
    I am running a SBS 2008 server. It's setup as the domain controller for the network. After a reboot, the Telephony service (and all services that depend on it) refuses to start under the Network Service account. The error given is: Error 1297: A privilege that the service requires to function properly does not exist in the service account configuration. You may use the Services Microsoft Management Console (MMC) snap-in (services.msc) and the Local Security Settings MMC snap-in (secpol.msc) to view the service configuration and the account configuration. This has caused all the network services not to be accessible e.g. terminal services, VPN (RRAS), SQL Server instances. The SSH daemon I have running on the box will accept connections only from localhost, but won't respond on the network. After searching around, the only advice I could find was to grant the Network Service account these permissions: Adjust memory quotas for a process Replace a process level token I set those permissions on both the Default Domain Policy and the Default Domain Controller Policy, but it seemingly had no effect. Most of the services will start if I change them to run under the Local System account, but that didn't make them accessible on the network. I even tried removing the Routing and Remote Access Services feature, rebooting and reinstalling it, but the issue remains. Any ideas?

  • Using GitOAuthPlugin for Jenkins - not working as expected

    - by Blundell
    I need some clarity and maybe a fix. I'm using this plugin to authorise who views our Jenkins ci server: https://wiki.jenkins-ci.org/display/JENKINS/Github+OAuth+Plugin As I understand it anyone who is auth'd to view one of our github project's can also login to our Jenkins box. This works I thought it would also allow the person logging in to only view the Project that they have GitHub permission on. For instance. Three projects on GitHub (A,B,C). Three builds on Jenkins. User 1 has Git access to all 3 projects (A B C). User 2 has Git access to only 1 project (A). When logging into Jenkins: User 1 can see all 3 projects ( this works ) User 2 can only see project A The problem is User 2 can also see all 3 projects when they should only see 1! Have I got this correct, and if so is this a bug? I have the settings set in Jenkins configuration Github Authorization Settings. Here we have some admin users. One organization. And none out of the 4 checkboxes ticked. (User 2, is not an admin, is not part of the org). The plugin is open sourced here: https://github.com/mocleiri/github-oauth-plugin I was trying to get Jenkins to print me the Logs from the plugin but I also failed at viewing these (to see if there was an issue). I followed these instructions: https://wiki.jenkins-ci.org/display/JENKINS/Logging It's the same concept as outlined below but using GitHub rather than manually selecting users: https://wiki.jenkins-ci.org/display/JENKINS/2012/01/03/Allow+access+to+specific+projects+for+Users%28Assigning+security+for+projects+in+Jenkins%29 Have I got this right or wrong? Is it possible to auth a Jenkins user to only see one project?

  • Start Menu Shortcuts resisting reorganisation

    - by seusr
    Running Win7. The Start Menu was getting too big, so I've navigated to C:\ProgramData\Microsoft\Windows\Start Menu\Programs and created some sub-folders in various categories [image editors, system utilities, media players, security for example] in which to group the shortcuts. Having created the group folders, I've dragged and dropped the Start Menu shortcuts into them. However it seems all Start Menu shortcuts are not alike. Some programs, their shortcut folders having been moved from the Start Menu, spawn NEW [but empty] folders bearing their company names in the top level of the Start Menu eg AVICodec Some programs don't have Start Menu shortcut folders that can be seen in WinExplorer [or equiv] at all, even though they turn up under the Start Menu itself. It seems these can be moved where they are visible i.e. in the Start - All Programs by dragging and dropping not just onto the desired folder but by hovering to expand the desired folder and then dropping between other shortcuts there. Eg Daum, Format Factory That's not such a problem, but why it's happening is a mystery. What's going on, and how to make these shortcuts behave normally or otherwise control them properly?

  • Error with Apache, Nagios and Snorby integration

    - by user1428366
    I'm trying to use apache to serve two different websites (Nagios and Snorby). The problem is that when I try to see the "/snorby" website, apache sends me the "It works" page. If I try to access to "/nagios" it works perfectly. Snorby is running under ruby passenger .This are the config files. <VirtualHost *:80> ScriptAlias /nagios/cgi-bin "/srv/nagios/sbin" <Directory "/srv/nagios/sbin"> # SSLRequireSSL Options ExecCGI AllowOverride None Order allow,deny Allow from all # Order deny,allow # Deny from all # Allow from 127.0.0.1 AuthName "Nagios Access" AuthType Basic AuthUserFile /srv/nagios/etc/htpasswd.users Require valid-user </Directory> Alias /nagios "/srv/nagios/share" <Directory "/srv/nagios/share"> # SSLRequireSSL Options None AllowOverride None Order allow,deny Allow from all # Order deny,allow # Deny from all # Allow from 127.0.0.1 AuthName "Nagios Access" AuthType Basic AuthUserFile /srv/nagios/etc/htpasswd.users Require valid-user </Directory> </VirtualHost> And the other one is this: <VirtualHost *:80> #Alias /snorby "/var/www/snorby-2.6.0/public" # !!! Be sure to point DocumentRoot to 'public'! DocumentRoot /var/www/snorby-2.6.0/public <Directory /var/www/snorby-2.6.0/public> # This relaxes Apache security settings. AllowOverride all # MultiViews must be turned off. Options -MultiViews </Directory> </VirtualHost> If I disable the Nagios webpage, the Snorby webpage works. I think the problem is Snorby because when I try to access to the Ip address with Nagios page disable, the webapplication redirects me to http:// myserverip/dashboard. Can anyone help me please? Thank you so much! Regards

  • DFSR NTFS Permissions Not Working!??!

    - by megadood
    I have two windwos 2008 standard servers running DFSR okay. I can create a file on one server, it is replicated to the other okay etc. I have the namespace shared folder on each server shared with full control administrators / everyone change/read permissions. I then browse to the folder on server 1 e.g.\server1\namespace\share\folder1. I right click the folder, and configure the NTFS permissions as I would like for example Adminsitrators Full Control / One User Read/Write Access / No other users in the user list. I save this and then double check the second server e.g. \server2\namespace\share\folder1. I right click the same folder name as before and can see the NTFS permissions have replicated accordingly. I right click the folder and go to properties - security - advanced - effective permissions and select a user that shouldnt be able to get into that folder e.g. testuser. It agrees with the NTFS permissions and shows that testuser has no ticks next to any permissions so should be denied access. I logon to any network PC or the server as testuser. Browse to \server1\namespace\share\folder1. It lets me straight in, no access denied messages. The same applies to server2. It seems as thought all my NTFS permissions are being ignored. I have 1 DFS share and then all the subfolders are a mixture of private folders and public folders so need the NTFS permissions to work ideally. Any idea whats going on? Is this normal? From my tests all users can access any DFSR folder under the namespace\share which is quite worrying. Thanks
